    (University of Dar es Salaam, 2008) Masaka, Tebogo Larry
    vopo Basin of Botswana, in a semi-arid region supports mi-arid region supports more than 60% of elation of Botswana and all administrative bodies hence initiative bodies hence its vulnerability in sustainable water resources. Ever growing water demand growing water demands and their skewed hical distribution in the basin exert immense pressure well immense pressure on the scarce water of the basin. In this study, an assessment on the status assessment on the status of water resources in the Limpopo Basin of Botswana was performed. Thana was performed. This was done by a I mixture of social research and statistical methods to re statistical methods to reveal the alarming 1 the water resources of the basin.
